The ending begins tomorrow night with the Waters of Mars. There will be three more episodes and then David Tennant will cease to be Doctor Who with "The End of Time", Parts I & II. In my extended involvement with the Doctor, I have been through many transitions since the 1960s, but Tenant created the best Doctor ever. I will miss him. In fairness to this creation of one timelord in one rather odd mode of transportation, I have promised two things: I won't read any of the spoilers and I will give the next incarnation a chance to become a great doctor.
Still there will be mourning and I fully expect more than a few tears to be shed, not to mention the gnashing of teeth and screams of outrage over the loss. When you give a great actor a great role, then wonderful things happen. David Tennant is a marvelous actor and Doctor Who may be one of the iconic characters of all time. One of these days, I may have the opportunity to see Mr. Tennant play Hamlet as he has done in Great Britain. Until then, thank you for this Doctor Who. Oh how you ran!!
